Large number calculation
the average household uses 5 bags of sugar per household per month. each bag of sugar weighs 4 pounds.
assume that that there are 2 people in each household on average and that the us population is 300 million
round answers to three significant digits except last answer.
example: 450,543,929 becomes 4.51e8 whre 4.51 is the significant digits.
how many pounds of sugar does the us consume per month?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
